Occurrence and number of infusoria of stomach (Ciliophora, Ciliata) in elk (Alces alces l.) of the Chelyabinsk and Omsk populations

Korchagina Tatyana Аleksandrovna

The article presents original data on the number and frequency of occurrence of infusoria in different parts of the stomach of elk in the Omsk and Chelyabinsk populations. Special attention is paid to the dependence of the abundance of protozoa on their distribution in the stomach. In the course of the work, a comparative analysis of the species composition of the infusor population of pre-ventricle moose of both populations was performed using the generally accepted coefficients-the Zhakkar-Malyshev coefficient (Kj-m) and the Chekanovsky – Sorensen faunal community index (Ics). The study shows that the rumen as the main place of formation and development of communities of endobiont infusoria from all the pre - ventricles of moose hosts is of priority importance for the species composition, occurrence and abundance of individual protozoan species.
